1-10. Default is 10.
<r2> is used to represent the maximum number of S frames that are used to acknowledge I
frames at uplink direction (A3LA-RM->IWF) and can take on the following values:
1-10. Default is 10.
<t4> is used to supervise the re-sequencing of misordered frames. The values are defined to be
the earliest instant to consider a tardy frame as lost. It can take on the following values:
20-255 (in 10-ms unit). Default is 25.
<mode> is used to indicate the mode of operation and can take on the following values:
0
unacknowledged mode of operation
1
acknowledged mode of operation (default)
NOTE: For the proper operation of the IRLP procedures, t2 should be less than t1 and 2*t4
should be less than t1.
Read Command: +WIRLP?
Query the actual IRLP parameters resulting from the negotiation (XID exchange) at the start of
the most recent data call. Note that these may differ from the desired parameters set using
“+WIRLP=…”; from power-up they are set to hardcoded defaults, and will only change as the
result of the negotiation. The response is in the form:
+WIRLP: <ver>, <k1>, <k2>, <t1>, <n2>, <t2>, <r1>, <r2>, <t4>, <mode>
Test Command: +WIRLP=?
List the supported IRLP parameter settings. The response is in the form:
+WIRLP: (supported <ver>s), (supported <k1>s), (supported <k2>s), (supported <t1>s),
(supported <n2>s), (supported <t2>s), (supported <r1>s), (supported <r2s), (supported
<t4>s), (supported <mode>s)
A.8.81 +WFRNG – Force IRLP Renegotiation
Set Command: +WFRNG=<frng>
Set forced renegotiation of IRLP parameters.
<frng> can take the following values:
0
Do not renegotiate (default)
1
Renegotiate
2
Disconnect
Read Command: +WFRNG?
Query the current parameter setting. The response is in the form:
+WFRNG: <frng>
Test Command: +WFRNG=?
List the supported parameter settings. The response is in the form:
+WFRNG: (supported <frng>s)
A.8.82 +WTM – IRLP Test Mode
Set Command: +WTM=<tm>
